“…Control plants were maintained for the same period of time on the non-salinized reference medium. Mature leaves were collected (C1, C2, C3 and C4) for analyses at 32, 36, 40 and 44 DAS Previous reports devoted to characterization of biochemical indicators associated with different levels of salt tolerance in genotypes of Cucumis melo (Yasar et al 2006, Kusvuran et al 2007 showed that anti-oxidant defence systems of leaves consisting in constitutive and salt-induced changes of activities of ascorbate peroxidase, glutathione reductase and catalase and ascorbic acid content were significantly higher in the salt tolerant Midyat than in the salt sensitive Yuva. In accordance with such observations the amounts of Na + and Cl -were lower, while those of K + and Ca 2+ were higher in the tolerant Midyat than those found in the saltsensitive Yuva (Yasar et al 2006, Kusvuran et al 2007).…”

In the present study, we have compared the magnitude of the changes induced by salinity in the amounts of citrulline and proline occurring in the leaves of the varieties, assuming that they could behave as biochemical indicators of the ability to withstand saline conditions through their possible involvement as compatible solutes or scavengers of ROS (reactive oxygen species).…”

“…In spite of the fact that wild watermelon was not induced to accumulate citrulline in response to salinity (Kawasaki et al 2000) we have hypothesized that citrulline itself and/or its metabolism could be involved as metabolic determinant(s) involved in salt tolerance of melon plants whose growth and agronomic yield are known to be drastically restricted even at low salinity (Navarro et al 1999, Sagot 2005. It was reported that salt tolerance in melons is dependent on cultivar traits and there are sensitive and tolerant ones (Shannon and Francois 1978, Yasar et al 2006, Kusvuran et al 2007.…”

Citrulline has been recently shown to behave as a novel compatible solute in the Citrullus lanatus (Cucurbitaceae) growing under desert conditions. In the present study we have investigated some aspects of the relationship which might occur in leaves of melon seedlings, also known to produce citrulline, between the capacity to accumulate this ureido amino acid and salt tolerance. With this end in view, salt-induced changes at the citrulline level have been compared in two melon genotypes exhibiting contrasted abilities to withstand the damaging effects of high salinity. Progressive salinization of the growing solution occurred at 23 days after sowing. The final 250 mmol/l external NaCl concentration was reached within 5 days and further maintained for 16 days. In response to this treatment, it was found that the citrulline amount increased in fully expanded leaves of both genotypes according to different kinetics. The salt tolerant genotype Midyat was induced to accumulate citrulline 4 days before the salt sensitive Yuva and as a consequence the final amount of this amino acid was twice higher in the former than in the latter. Compared with citrulline, the free proline level was found to be relatively low and the changes induced in response to the salt treatment exhibited different trends according to the genotypes under study. Thus at the end of the treatment mature leaves of the salt sensitive Yuva contained higher amount of proline than those of Midyat. The changes in the calculated molar ratio between citrulline and free proline suggested that salt tolerance might be associated with high values for this ratio and vice et versa for sensitivity. The interest of citrulline as a biochemical marker for salt tolerance of melon genotypes is discussed.

“…The reduced development of lemon balm plants subjected to salinity is probably as a result of the NaCl action on plants that causes the disturbance in their water relations, especially with respect to turgor, due to changes in osmolarity (Yasar, 2006;Hussain et al,2011). It means that there is a reduction in water absorption, and consequently, a decrease in water content in the plant tissue and in the turgor, as observed in our work (Fig.…”

Agricultural crops are severely affected by salinity. Recent studies have shown that salt stress signaling components affect plant metabolism and stimulate the accumulation of organic osmolytes and antioxidant substances. This work aimed at assessing the growth and development of lemon balm, Melissa officinalis L., subjected to salt stress, as well as its antioxidant response, essential oil composition, and essential oil yield (%). A completely randomized experimental design was conducted under greenhouse conditions, where 30-days-old lemon balm plants were treated with different NaCl concentrations (0, 50, 100, 150 and 200 mM) for sixty days. The highest concentrations (150 mM and 200 mM NaCl) caused significant reductions in shoot height, shoot fresh mass, relative water content, water activity and chlorophyll production due to changes in osmotic activity. The activities of superoxide dismutase (SOD) and catalase (CAT) increased in plants subjected to salinity. In addition, membrane damage (DM) increased with increase in NaCl concentration. The yield of the essential oils decreased but the number of compounds increased in all the NaCl treatments. The compounds neryl-acetate and geranyl-acetate were detected at 100, 150 and 200mM NaCl, suggesting that under salt stress, lemon balm plants activate the metabolic pathways for the production of terpenoids, consequently producing monoterpenes. Salinity negatively affected most of the parameters evaluated in lemon balm plants. Our results show that lemon balm plants are tolerant to low concentrations of salinity (up to 50mM) as proved by their distinct metabolic responses.

“…These landraces are under cultivation for hundreds of years in arid and semi arid regions of Iran, which salinity is the one factor limiting the growth and production of agricultural products. The 'Galia' F1 as a salt-tolerant cultivar (Yasar et al, 2006), was included for comparison. The effects of salinity stress on seed germination parameters, hydrogen peroxide content, lipid peroxidation and some antioxidant enzymes (POD, APX and SOD) in these landraces were studied.…”

Although salt stress affects all growth stages of a plant, seed germination and seedling growth stages are known to be more sensitive for most plant species. The current research was carried out to find the most effective indicators when screening melons for salt tolerance. For this purpose, a factorial experiment as a completely randomized design was performed in order to investigate the effects of salinity (0, 20, 40, 60 and 80 mM NaCl) on seed germination parameters, hydrogen peroxide content, lipid peroxidation and some antioxidant enzymes (guaiacol peroxidase, ascorbate peroxidase and superoxide dismutase) in five Iranian melon landraces and one melon cultivar 'Galia' F1 at early seedling growth stage. The 'Galia' F1 was included for comparison as a salt-tolerant cultivar. The data collected from all salinity treatments across six landraces were used for analysis of variance and principal component analysis (PCA) using SPSS software as well as for obtaining Pearson's correlation coefficients (r) among all physiological parameters. Obtained results indicated that averaged all landraces across all treatments, increased NaCl significantly affected all the parameters measured. In all landraces, salt tolerance index (STI) decreased as the salt concentrations increased. The principal component analysis revealed variations among the traits and determined four main factors that explained 97.53% of the total variance. Simple correlation coefficient analyses showed the existence of significant positive and negative correlations among characteristics. Our study suggests that the salt tolerance index and principal component analysis can be used as accurate and easy indicators when screening melons for salt tolerance.
